What powers the QUAD 1000HDD on a shaft job - do I need batteries?

There are no internal batteries. The QUAD 1000HDD runs on 12 VDC through the supplied 20-foot cord with alligator clips, so any 12-volt battery on site will do. If AC is available, the optional 1140 power converter runs the laser from 90 to 260 VAC and senses the voltage automatically.

What is the difference between the QUAD 1000HDD and the QUAD 1000HDU?

Beam direction only. The HDD shoots a nadir beam straight down. The HDU shoots a zenith beam straight up and adds a short downward plummet beam for setting up over a point, where the HDD uses a survey prism on its 5/8-11 top thread instead. Accuracy, range, housing, case, cord, trivet and targets are identical.

How accurate is the QUAD 1000HDD?

Plus or minus 5 arc seconds, which is about plus or minus 1/32 inch over 100 feet or .793 mm over 30.48 metres. Over a 1,000-foot drop that is roughly plus or minus 5/16 inch. The spot measures .500 inch at the lens, 0.80 inch at 500 feet, 1.10 inches at 1,000 feet and 1.40 inches at 1,500 feet, so read to the centre of the spot.

Will temperature change in a shaft affect the reading?

No. The instrument uses electronic servo self-levelling with variable temperature compensation. It senses ambient temperature change while running and continually recalibrates itself, so readings stay consistent through a shift.

How do the QUAD 1000HDD alignment targets work?

Two translucent bulls-eye targets come in the box, readable from either face. One has a quarter-inch hole through the centre so the beam passes through and several targets can be read at once. Four template notches allow floor and deck marking, and two mounting holes each allow custom mounting. Turn the laser off before centring on a target with an optical plummet instrument, because magnifying optics raise the eye hazard.

Is the QUAD 1000HDD waterproof?

Yes. The housing is sealed to IP67 and purged and charged with dry nitrogen, inside quarter-inch aluminium with a hard-coat anodised finish. The housing must never be opened. Warranty is 24 months on parts and labour.

Q: What kind of platform does the QUAD 1000HDD need?

Flat, level and rigid. Most crews fabricate and weld a steel plate platform with an oversized hole for the beam, position it, then set the trivet on top and tie it down through the anchor slots.

Product Description
Warranty Information

When your control point is at the bottom of a shaft, you need a beam that goes straight down and stays there. The LaserLine QUAD 1000HDD projects a nadir laser beam vertically downward to 2,000 feet (609.6 m) and holds it to ±5 arc seconds — about 1/32 of an inch over 100 feet. It mounts on a job-built platform over your opening and gives you plumb control the whole way down. Built for shaft alignment, mining, tunnelling and deep foundation work, in a sealed ¼-inch aluminium housing purged and charged with dry nitrogen to IP67.

Why Crews Choose the QUAD 1000HDD

Nadir Beam to 2,000 Feet

One downward beam carries plumb control 609.6 metres into the hole — the full depth of a shaft without re-establishing control on the way down.

Prism Mount on Top

A 5/8-11 female thread on the top plate takes a survey prism, so you can traverse the laser across your platform with a total station and set it precisely on the plumb point.

±5 Arc Second Accuracy

±1/32 inch per 100 feet (.793 mm per 30.48 m). The spot measures .500 inch at the lens and about 1.40 inches at 1,500 feet.

Temperature Compensated

Electronic servo self-levelling senses ambient temperature change while running and continually recalibrates, so a reading taken hours into a shift matches the one taken at setup.

Sealed Against the Job

Purged and dry-nitrogen filled to IP67 inside a heavy ¼-inch aluminium housing with a hard-coat anodised finish. Dust and water are not a factor.

One Button, Ten Seconds

Press power and the unit self-levels in under ten seconds. The beam blinks while levelling and goes steady when it is in spec. Battery and level status show on a backlit LCD.

Questions Crews Actually Ask

What powers it on a shaft job — do I need batteries?

There are no internal batteries to forget to charge. The QUAD 1000HDD runs on 12 VDC through the supplied 20-foot cord with alligator clips — any 12-volt battery on site will do, including a vehicle or equipment battery. If you have AC at the collar, the optional 1140 power converter runs the laser from 90–260 VAC and senses the voltage for you. That is the whole power story: a battery and a cord, or a converter and a wall.

What is the difference between the HDD and the HDU?

Beam direction, and only beam direction. The HDD shoots a nadir beam straight down; the HDU shoots a zenith beam straight up. The HDU also carries a short downward plummet beam for setting up over its point, where the HDD uses a survey prism on its 5/8-11 top thread instead. Accuracy, range, housing, case, cord, trivet and targets are identical.

How do I get the laser directly over my plumb point?

Thread a survey prism onto the 5/8-11 thread on top of the instrument, attach the laser to the rotational mount on the trivet, and traverse it across your platform with a total station until it sits on the plumb point. Level the bulls-eye bubble with the three levelling screws as you go, then lock the screws and tie the trivet down through the anchor slots.

What does the platform need to look like?

Flat, level and rigid — that is the one constant across every job. Virtually every project fabricates its own: most crews weld a steel plate platform with an oversized hole for the beam, position it, then set the trivet on top and tie it down. Everything else about the setup varies site to site.

How accurate is it in real terms?

±5 arc seconds is about ±1/32 of an inch over 100 feet, or .793 mm over 30.48 metres. Over a 1,000-foot drop that is roughly ±5/16 of an inch. The spot grows as it travels — .500 inch at the lens, 0.80 inch at 500 feet, 1.10 inches at 1,000 feet, 1.40 inches at 1,500 feet — so read to the centre of the spot on the bulls-eye target, not to its edge.

Will temperature swing in a shaft throw the reading off?

That is exactly what the electronic temperature compensation is for. The instrument senses ambient temperature change while it is running and continually recalibrates itself, so a reading taken hours into a shift matches the one taken at setup. Shafts and tunnels are the environment this was designed around.

How do the alignment targets work?

Two come in the box. They are translucent, so you can read the spot from the back as well as the face, and the bulls-eye rings make centring easy. One target has a ¼-inch hole through the centre so the beam passes through and you can read several floors at once. Four template notches let you use them for floor and deck marking, and two mounting holes each allow custom mounting. One safety note from LaserLine: turn the laser off before centring on a target with an optical plummet instrument — magnifying optics raise the eye hazard.

Can it get wet and dusty?

Yes. The housing is sealed to IP67 and purged and charged with dry nitrogen, inside ¼-inch aluminium with a hard-coat anodised finish. Never open the housing — that breaks the nitrogen charge and exposes you to the laser source. Warranty is 24 months on parts and labour.
